ELECTRIC SIGN.

SPECIFICATION forming part of Letters Patent No. 738,489, dated September 8, 1903 Application filed December 30, 1902. Serial No- 137,098. (No model.)

To all whom it may concern.-

Be it known that I, BERT E. SALISBURY, a citizen of the United States, residing at Syracuse, in the county of Onondaga and State of New York,have invented certain new and useful Improvements in Electric Signs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an electric sign and a receptacle particularly designed to form a part thereof, and has for its object to produce a sign which may be simply and economically constructed, with a series of receptacles oompactly arranged and secured adjacent to each other on its back and easily wired in multiple by a single pair of wires. The receptacle devised therefor has a cylindrical body adapted to extend through a corresponding hole in the supporting-board or the sign, so that lamps inserted from the front may form a substantially continuous line, forming letters or other designs.

My invention will be understood by reference to the drawings herewith, in which the reference-numerals of the specification indicate corresponding parts in all the figures.

Figures I and II are respectively front and rear elevations of my sign. Fig. III is an enlarged side elevation of the receptacles in position. Fig. IV is a vertical section of a receptacle in position. Fig. V is an enlarged rear plan of a wired receptacle.

In the figures, 1 indicates the supportingboard, of suitable material and construction, to the rear of which are secured, each by a pair of screws, my receptacles, especially designed for this purpose, having their body portions fitting holes inthe board. These re oeptacles consist, essentially, of a porcelain base having a substantially disk-shaped base 3, of uniform and sufficient thickness to give strength, and of a cylindrical body at, having substantially straight sides and of sufficient diameter for the mouth to receive the lamptcrminals 5 and 6, the central terminal being preferably provided with the contact-spring The base is formed with opposite perforated ears for the two securing-screws and with cavities 11 and 12', one straight, to receive the wire-terminal 13, retained in posisition by engagement of the screw-lip of the central terminal 6 and provided with one of the binding-screws 18, cooperating with inclined end 17, and the other cavity 12 curved, to receive the opposite terminal 14, retained in position by two rivets or screws 15, also engaging with and supporting the screw-ring lamp-terminal 5. This curved wire-terminal also carries the other binding-screw 18 and has the inclined end 17, against which the screw binds the stripped portion of the linewires 20 21. These receptacles are simple in form and economical to construct, being of the smallest size consistent with strength, and are adapted to be arranged compactly, as best shown in Fig. II, with their respective axes through the ears arranged at an angle to the line of the lamps and their wire-terminal axes substantially at a right angle to these earaXes, whereby they are compactly arranged, so that the lamps inserted from the front are almost in contact and make substantially a continuous illuminated line, particularly desirable for forming outlines of letters or of other designs, as may be desired.

My sign is simple and economical to construct and install,also easily and conveniently wired by the single pair of wires brought through porcelain tubes 23, arranged at any desirable point in the margin 24, and when completed a protecting-back may be secured to the margin, covering and protecting all the parts.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. I11 an electric sign, a suitable supporting-board and porcelain receptacles secured adjacently on its back, said receptacles having fiat, substantially circular bases, adapted to lie snug and compactly against the back of the boards, cylindrical bodies extending outwardly from said bases, through the board, integral ears on the bases perforated for the securing-screws, lamp-terminals arranged in mouths formed in the bodies, and wire-terminals arranged in depressions formed on the back of the bases, said terminals-bein g adapted to receive the-opposite live wires.

2. In an electric sign, the combination with a supporting-board formed with a series of adjacent holes, a margin around the edge of the board on its rear and a protecting-back secured to the margin of receptacles for ineandescent lamps secured to the rear of the board and having substantiallycircular bases, integral cylindrical bodies fitting the holes and projecting outwardly therethrough, metallic lamp-terminals arranged in the mouths of said bodies and wire-terminals arranged on the bases and connected to the respective lamp-terminals, and line-wires connected to the respective wire-terminals.

3. In an electric sign, the combination with a supporting-board formed with a series of adjacent holes, of receptacles formed with sub stantially circular bases, opposite, integral perforated ears on the bases and integral bodies fitting the holes, lamp-terminals arranged in mouths in the bodies and wire-terminals on arranged with the ear-axes inclined to the axis of the series.

4. A receptacle for an electric sign having in combination, a substantially circular porcelain base of uniform thickness, opposite, integral ears on said base for the two securing-screws, an integral cylindrical body portion on the base having a mouth to receive the lamp-base, the base being provided on its back with one straight depression and one substantially semicircular depression, lampterminals fitted to the mouth, a wire-terminal fitted to the straight depression and connected to the central lamp-terminal, a wireterininal fitted to the semicircular depression and connected to the screw-ring terminal, and binding-screws on each lamp-terminal.

In testimony whereof I afiix my signature in presence of two witnesses.

BERT E. SALISBURY.
